Description

Technical Field [0001] The present invention relates to a common entrance access control system and method,

The present invention relates to a system and method for accessing a common entrance, and more particularly, to a technology for automatically opening a door using a Bluetooth signal and accurately checking an entrance even when a plurality of persons enter and exits.

Common entrances in apartment houses and office buildings are normally closed, limiting access by outsiders. In other words, if the doorway is open all the time, there is a lot of workmen go in and stick advertising leaflets indiscriminately. Of course, for the prevention of crime, entrance control is necessary.

In order to open the doors of these common porches, the most common method is to input the password through the lobby phone. However, the input method of the password is troublesome and the possibility of the password leakage is high.

For this purpose, a technology has been proposed in which residents are given an RFID or NFC card and the door is opened by card reading. However, the inconvenience of having to remove the card for tagging remains.

The beacon device periodically outputs a beacon signal having a unique ID. The beacon device can be manufactured in various forms such as an accessory type and a card type. Hereinafter, the smart cards 21, 22, and 23 will be described as a representative of the beacon device, but a card-shaped beacon device is not necessarily used.

In the case of the user terminals 11, 12 and 13 of the user equipments, the Bluetooth communication and the authentication and entry fact recording can be performed through a dedicated application installed in advance. To this end, the operation system 100 controls the user terminals 11, 12, 13) side, or can respond to a service provided by a dedicated application. The configuration of the user terminals 11, 12, and 13 will be described with reference to FIG.

The operating system 100 may be operated in the form of a building, a building, a building, a building, or the like. If the small apartment house alone operates the operating system 100, the functional configuration of the operating system 100 may be mounted on the APs 30 and 40 or installed near the APs 30 and 40.

That is, the common entrance / exit control system to be provided in the present invention may refer to the APs 30 and 40 themselves or may include both the APs 30 and 40 and the operation system 100. According to the present invention, the common entrance entrance control system according to the present invention may also include user equipment (11, 12, 13, 21, 22, 23).

Hereinafter, with reference to FIG. 2, a common entrance entrance control system according to an embodiment of the present invention and the configurations associated therewith will be described in more detail.

First, the operation system 100 includes a communication unit 105, a service operation unit 110, and a database 115.

The communication unit 105 is provided for connecting a communication channel with the APs 30 and 40 and the user terminals 11, 12 and 13 through a wire / wireless network and transmitting / receiving data.

The service operating unit 110 confirms whether the user is a user registered in the database 115 through the unique identification number (beacon ID or secret key) transmitted from the AP 30 or 40, To store in the database 115 access records for returning home or leaving from the user terminals 11, 12,

The APs (Access Points) 30 and 40 perform Bluetooth communication with the user equipment, determine whether the user is an authorized user through the unique identification number of the user equipment, output an open signal to the door driving unit 60, It is provided for storing access records. User authentication and access record storage may be done by the APs 30 and 40 themselves, but may also be done in conjunction with the operating system 100.

The APs 30 and 40 are installed on the outdoor side and on the indoor side, respectively. The first AP 30 may be installed only on the outdoor side and the second AP 40 may not be provided on the indoor side and only a motion sensor (not shown) or a separate button may be provided. That is, in order to enter the room outdoors, it is necessary to confirm whether the user is an authorized user. However, since the authentication process is not necessarily required when an outsider (visitor) When an event occurs, the door 70 can be opened without any separate authentication.

The APs 30 and 40 include first BLE modules 31 and 41, second BLE modules 32 and 42, third BLE modules 33 and 43, controllers 34 and 44, memories 35 and 45, (36, 46). Here, the configuration of the first AP 30 and the configuration of the second AP 40 are the same, and 'a' and 'b' are added after the configuration name for identification. Hereinafter, the functional configuration of the first AP 30 will be described, and the description of the same functional configuration of the second AP 40 will be made obviously through the description of the first AP 30. [

A plurality of BLE modules a (31, 32, 33) are provided for performing Bluetooth communication with the user equipment. A plurality of BLE modules a (31, 32, 33) are provided for checking whether or not a plurality of users enter and exit according to the type of the user equipment, and the operation modes of the BLE modules a (31, 32, 33) different.

First, the first BLE module a (31) operates in an Advertiser mode (publishing mode) in which a Bluetooth signal is transmitted at predetermined time intervals. In other words, when operating in the Advertiser mode, only the signal is transmitted and not connected (paired) with the external device.

The second BLE module a (32) operates in a peripheral mode capable of both transmitting and connecting Bluetooth signals. That is, the second BLE module a (32) can transmit its unique signal and be connected to a specific user terminal (11, 12, 13). When operating in Peripheral mode, it can only be connected to one device, and after it is connected, it stops sending signals (posting). Also, the second BLE module a (32) receives the secret key from the user terminal (11, 12, 13).

The third BLE module a (33) operates in the Observer mode for scanning a specific Bluetooth signal (beacon signal). In the case of the smart cards 21, 22, and 23, only a self-signal is transmitted and a connection (pairing) with other devices is performed. It does not. Therefore, the third BLE module a (33) operates in the Observer mode and acquires only the signal transmitted (posted) from the smart cards (21, 22, 23).

Here, the signal output from the first BLE module a 31 or the second BLE module a 32 may be scanned by the third BLE module a 33. If the signal is excluded from the scan result through the programming setting of the controller a 34 do.

Meanwhile, the user terminals 11, 12, 13 and the smart cards 21, 22, 23 can be used as the user devices. The user terminals 11, 12, 13 operate in the Central mode for scanning and connecting the Bluetooth signals And the smart cards 21, 22, and 23 operate in the Advertiser mode in which only the self-signal is transmitted.

The controller a 34 judges whether the user is an authorized user through the unique identification number (beacon ID or secret key) of the user equipment acquired from the BLE module a 31, 32, 33 and transmits the door 70 to the door driving unit 60 side. It outputs an open signal, judges whether or not it is returning from the home, and stores the access record.

The memory a 35 is provided for storing the unique identification number of the permitted user equipment or for storing (updating) the access record.

It is possible for the first AP 30 to perform the user authentication and the access record storage through the control unit a 34 and the memory a 35 by itself, After sending the unique identification number to the system 100 and returning the authentication result, the opening signal can be output to the door driving unit 60, and the access record can be transmitted to the operating system 100 and stored in the database 115 You may.

The communication processing unit a 36 is provided for connecting a communication channel with the operating system 100 through a wire / wireless network and transmitting / receiving data.

Meanwhile, the first BLE module a (31) operating in the Advertiser mode and the third BLE module a (33) operating in the Observer mode may be implemented as separate chips, but the controller a (34) It may be controlled by software to perform each mode operation. For example, after implementing the integrated BLE module, the control unit 34 can sequentially perform signal posting and scanning in units of seconds.

Each of the functional configurations of the common entrance / exit control system according to the embodiment of the present invention described above will be further specified by the common entrance / exit control method described below with reference to FIG. 3 to FIG.

3 is a flowchart illustrating a user equipment registration process in the common entrance control method according to an embodiment of the present invention. That is, the common entrance / exit control system shown in FIG. 1 and FIG. 2 can authenticate the pre-registered user device, open the door 70 and record whether or not the user enters or exits.

The smart cards 21, 22, and 23 for outputting beacon signals (bluetooth signals) among the user devices can be paid to the elderly or children who are not familiar with using smart devices such as a smart phone or a tablet PC. The smart card 21, 22 or 23 having the unique identification number registered in the system 100 or the AP 30 or 40 is paid or the unique identification number of the corresponding smart card 21, May be registered in the system 100 or the APs 30 and 40.

Accordingly, a process of installing a dedicated application in a user terminal 11, 12, 13 of a smart phone or a tablet PC and registering it through a separate authentication process will be described below. For convenience, the first user terminal 11 will be described as a reference.

First, the user installs a dedicated application in the first user terminal 11 (S305). The dedicated application may be provided in the operating system 100 and registered in the application store. Accordingly, the dedicated application can be downloaded through the first user terminal 11 by accessing the application store.

Thereafter, the first user terminal 11 may drive a dedicated application to access the operating system 100, enter resident information (e.g., lake, lake, name), and perform predetermined resident authentication < S310 >. Various methods can be applied to resident authentication. The service operating unit 110 transmits the authentication number to the first user terminal 11 in a state where the user terminal number is stored in the database 115 of the operating system 100, Or a method of inputting the password, or a method of inputting a password for authentication paid only to a resident.

When the resident authentication is completed in the service operating unit 110 of the operation system 100, the door key 70 is provided with the door 70 open secret key in cooperation with the communication unit 105 to the first user terminal 11, 1 < / RTI > At the same time, the service operating unit 110 of the operating system 100 transmits the secret key provided to the first user terminal 11 and the Bluetooth ID, terminal number, and resident information acquired from the first user terminal 11 to the database 115, And ends the user registration < S320 >.

The service operation unit 110 of the operation system 100 transmits the BLE modules 31, 32, 33, 41, 42, and 43 of the first AP 30 or the second AP 40 to the first user terminal 11, To be stored. At this time, the operation system 100 may provide only the unique identification number of the APs 30 and 40 installed in the specific common porch through the resident information of the first user terminal 11, And may provide all of the unique identification numbers of &lt; RTI ID = 0.0 &gt;

FIG. 4 is a flowchart for explaining a process of authenticating a smart card and opening a door in the common entrance control method according to the embodiment of the present invention. FIG. 5 illustrates a signal flow between the AP and the smart card Fig.

That is, the process of automatically opening the door 70 and updating the outgoing record when the user having the pre-registered first smart card 21 leaves the room outdoors.

First, the first smart card 21 is a thin-film type card which generates a unique beacon signal (Bluetooth signal) at a predetermined time interval (Advertiser mode, publication), and can be easily carried in the form of a wallet or a necklace. Of course, the first smart card 21 may be equipped with a payment function through an IC chip, an NFC having high security, and an RFID tag using proximity tagging. In addition, the first smart card 21 may be an accessory type It can also be made.

The third BLE module b (43) of the second AP (40) installed on the indoor side of the common porch operates in the Observer mode (scan). The third BLE module b 43 of the second AP 40 can scan the first smart card 21 when the user having the first smart card 21 approaches the common porch for going out .

On the other hand, the controller b 44 of the second AP 40 determines whether it is within a predetermined distance based on the signal intensity of the first smart card 21 recognized by the third BLE module b 43 (S410). If it is confirmed that the user is within the predetermined distance in step S415, the controller b 44 confirms whether the user is a pre-registered user through the unique identification number (beacon ID) acquired from the first smart card 21, And outputs an opening signal to the door driving unit 60 when the user is the user.

Here, the registered user information, i.e., the resident list, is transmitted from the operating system 100 to each of the APs 30 and 40 and stored in the memories 35 and 45 in advance. The registered user information can be changed constantly according to the occupant's moving in or leaving, or the new registration of the smart card 21, 22, 23. To this end, the resident list can be updated in real time or at a predetermined time (day). In addition, the APs (30, 40) must have a list of all residents within the schedule management area. If it is a large apartment complex, the capacity of the resident list is increased, so that it can be transmitted in compressed form and updated.

If the registered user information (resident information) is stored in the APs 30 and 40, the control unit 44 of the second AP 40 registers the registered user information (resident information) stored in the memory b 45 and the registered user information User authentication can be performed by comparing the unique identification number of the card 21. In this case, even if there is no separate operating system 100 or if a failure occurs in the network with the operating system 100, user authentication is possible.

Of course, for user authentication, the control unit b 44 transmits the unique identification number (beacon ID) of the first smart card 21 to the operating system 100 side through the communication processing unit b 46, The service operation unit 110 may perform the user authentication through the information stored in the database 115 and return the information. However, in the case of a common entrance where frequent accesses are made, or when other beacon signals around the common entrance, rather than the beacon devices of the residents, are occasionally caught, overloading may occur during transmission and verification of all of the verified signals to the operating system 100 have. In this case, it is preferable to store the registered user information (residents list) in the APs 30 and 40 in the manner described above and check them immediately.

In addition, the control unit b 44 updates the outgoing record for the user (resident) using the first smart card 21 (S425). That is, the outgoing record is stored in the memory b 45 or the outgoing record is transmitted to the operating system 100 and stored in the database 115.

In the above description, when the user having the first smart card 21 leaves the room outdoors, the second AP 40 recognizes it and automatically opens the door 70 and updates the outgoing record. Of course, when returning to the room from outside the room, the same process is performed through the first AP 30 to automatically open the door 70 and update the home recording.

At this time, the process of authenticating the user can be omitted, unlike the case of returning home. In other words, there is no restriction when an outsider leaves the room while leaving the room, so that the door 70 is opened through a motion sensor or a button input. However, the present invention aims to provide a convenience of automatically opening the door (70) even if the occupant does not take any action, and to store the accessibility of the occupant so as to grasp the occupant status in the event of an emergency such as a fire. Therefore, residents must go through the process of updating the access record.

On the other hand, an algorithm for correctly determining whether or not the user is going out or going out can be further applied. In the simplest method, when the first smart card 21 is recognized first by the second AP 40, it is determined that the smart card 21 is out of the home.

However, there may be cases where the user goes out to the common entrance to go out, but goes home again without going out. In this case, since the first smart card 21 is first recognized by the second AP 40, it should not be determined immediately when going out.

For this special case, the first AP 30 and the second AP 40 interlock with each other to judge whether or not access is made. That is, the first AP 30 on the outdoor side and the second AP 40 on the indoor side are provided with a distance difference so that the AP 30 or 40 confirms whether the user equipment is recognized first, will be.

Accordingly, when the third BLE module b 43 of the second AP 40 recognizes the first smart card 21, the controller b 44 tracks the signal strength of the first smart card 21. At the same time, the first AP 30 also starts preparing to track the signal strength of the first smart card 21. [ For this purpose, the first AP 30 and the control units 34 and 44 of the second AP 40 may be interlocked with each other or may have separate integrated control means or the service operation unit 110 of the operation system 100 may intervene So that software control can be performed.

If the user normally goes out, the signal intensity of the first smart card 21 received at the third BLE module b 43 of the second AP 40 will gradually increase. If the user passes the entrance, the second AP 40 The signal will weaken and no more signal will be caught. The third BLE module a 33 of the first AP 30 recognizes the first smart card 21 and can recognize that the signal is progressively increasing. As the user moves away, the third BLE module a 33 recognizes The intensity of the signal will be reduced.

If the signal intensity of the first smart card 21 is stronger and stronger than that of the first smart card 21, then it is determined that the signal strength of the first smart card 21 becomes stronger and stronger at the first AP 30, (35, 45) or the database 115 of the operating system 100.

However, although the user approached the common porch and opened the door 70 at the second AP 40 recognizing the first smart card 21, the user may return to his / her home by turning his / her foot. Accordingly, the third BLE module b 43 of the second AP 40 recognizes the first smart card 21 and tracks the signal strength. However, unlike the previous example, the first AP 30 recognizes the first smart card 21 If it does not, or if it recognizes only a minute signal for a while, but the signal is stronger than a certain level, if it does not show a pattern that weakens, do not record it.

Thus, if the signal intensity of the first smart card 21 is tracked in the second AP 40 and the first AP 30, it is possible to accurately determine whether the user actually passes the common porch.

In the above, an example of judging whether or not the user has actually gone out has been described in the case of going out. However, in the case of returning home, the first AP 30 and the second AP 40 can track a signal in order.

In addition to the system using two APs 30 and 40, a motion sensor (not shown) and a foot sensor are installed in the indoor and the outdoor, respectively, and whether the motion sensor or the foot sensor is moved sequentially is checked. You can judge.

FIG. 6 is a flowchart illustrating a process of authenticating a user terminal and opening a door in the common entrance control method according to an embodiment of the present invention. FIG. 7 illustrates a signal flow between an AP and a user terminal Fig.

That is, the user of the first user terminal 11 registered in advance through the process of FIG. 3 described above automatically opens the door 70 to be returned to the room outdoors and updates the home register.

Prior to the description, the specific configuration of the user terminals 11, 12, and 13 will be described first with reference to FIG. In FIG. 7, the first user terminal 11 is represented by a block diagram, and the second and third user terminals 12 and 13 have the same configuration. In addition, 'c' is given as a division mark to the configuration name of the first user terminal 11, but it does not have a special meaning.

The first user terminal 11 may be a conventional smart phone or a tablet PC. However, a dedicated application is installed in order to be used for the common entrance entrance control as in the present invention, and all operations for opening and closing the entrance door and the entrance and exit are performed by driving a dedicated application. Therefore, the configuration of the first user terminal 11 shown in FIG. 7 may be a hardware configuration already installed in a smart phone or the like, and a part of the configuration may be a software configuration driven by installation of a dedicated application. However, FIG. 7 is a visualization of the components necessary for controlling the access to the common entrance.

The first user terminal 11 includes a communication module c 11-1, a Bluetooth module c 11-2, a distance determination unit c 11-3, an app control unit c 11-4, a storage unit c 11 -5) and a key input unit c (11-6).

The communication module c (11-1) is provided for connecting a communication channel with the operating system 100 through a wire / wireless network and transmitting / receiving information.

The Bluetooth module c (11-2) is provided for performing Bluetooth communication with the APs (30, 40). Specifically, the Bluetooth module c (11-2) scans the Bluetooth signal transmitted (posted) from the first BLE module 31, 41 and the second BLE module 32, 42 and connects the second BLE module 32, (Pairing). Also, the Bluetooth module c (11-2) can transmit a unique identification number (Bluetooth ID or secret key) to the second BLE module (32, 42).

The distance determination unit c 11-3 determines the distance between the first user terminal 11 and the APs 30 and 40 through the intensity of the Bluetooth signal transmitted from the first BLE module a 31 or 41 of the AP 30 or 40. [ Judge the distance.

The app control unit c (11-4) performs overall function execution for the common entrance control. That is, the app controller c (11-4) confirms whether the Bluetooth signal transmitted from the AP (30,40) is scanned in association with the Bluetooth module c (11-2) It is determined that the Bluetooth module c 11-2 is connected to the second BLE module 32 or 42. If the second BLE module 32 or 42 is connected to the second BLE module 32 or 42, To transmit the secret key stored in the storage unit c (11-5). In addition, the app control unit c (11-4) processes information for accessing or not entering the communication module c (11-1) to the operating system 100 side.

The storage unit c 11-5 is provided for storing the secret key, the unique identification number of the AP 30, 40, and the like. The secret key or unique identification number of the AP 30,40 may be stored by receiving from the operating system 100 in the course of installing a dedicated application and authenticating the resident.

The key input unit c (11-6) is provided for receiving various user information and commands. The key input unit c (11-6) may be a button or a touch screen integrally formed with the display.

Meanwhile, the first user terminal 11 may further include a Wi-Fi module c (11-7) for performing Wi-Fi communication. This will be described later with reference to FIG.

The specific operation process of the first user terminal 11 will be further specified through the entrance control process of the user shown in FIG.

The first BLE module a 31 of the first AP 30 installed on the outdoor side of the common porch operates in an Advertiser mode for transmitting a unique Bluetooth signal and the second BLE module a 32 is operated in the Peripheral mode, And operates in a mode of posting the Bluetooth signal and connecting with the first user terminal 11. [

Therefore, when the first user terminal 11 approaches the common porch, the Bluetooth module c 11-2 of the first user terminal 11 recognizes the origination signal of the first BLE module a 31 of the first AP 30 If the signal strength of the first BLE module a 31 is equal to or higher than a certain level in the distance determination unit c 11-3, the app controller c 11-4 transmits the Bluetooth module c 11 -2) and the second BLE module a 32 (step S610). Of course, since both the first BLE module a 31 and the second BLE module a 32 are scanned during the scanning operation of the Bluetooth module c 11-2, the first BLE module a 31 or the second BLE module a It is possible to determine the distance through any one of the outgoing signals. However, if the second BLE module a (32) is connected to another user terminal, the distance determining unit (11-3) always stops transmitting the first BLE module a (31 It is preferable to determine the distance using the signal strength of the signal.

Whether any of the bluetooth signals simultaneously scanned in the Bluetooth module c (11-2) is a signal to be tracked for distance determination can be distinguished through a unique identification number stored in the storage unit c (11-5). That is, when a dedicated application is installed in the first user terminal 11 through the process of FIG. 3 and user registration is performed in the operation system 100 through the resident authentication process, the storage unit c of the first user terminal 11 (11-5) stores the unique identification number of the AP (30,40) together with the secret key.

Therefore, the distance determination unit c 11-3 compares the unique identification number stored in the storage unit c 11-5 with the Bluetooth signal scanned by the Bluetooth module c 11-2 to determine whether the first BLE module a 31 It can be seen that the signal is a signal to be tracked for distance determination.

Of course, the unique identification number of the second BLE module a (32) to which connection is permitted is also registered in advance in the storage unit c (11-5).

When the Bluetooth module c 11-2 of the first user terminal 11 and the second BLE module a 32 of the first AP 30 are connected to each other, The control unit 34 of the first AP 30 receives the secret key via the second BLE module a 32 and then transmits the secret key to the first AP 30 (S620) whether the user is a registered user (i.e., a resident). If the controller a 34 confirms that the device is permitted to enter and exit, the door driver 60 outputs the opening signal of the door 70 <S625>.

The controller a 34 checks the registered user's terminal (resident information) corresponding to the unique identification number (Bluetooth ID or secret key) of the first user terminal 11 connected to the second BLE module a 32, (S630).

The registered user information including the unique identification number of the person authorized access is stored in advance in the memory a 35 of the first AP 30. The registered user information stored in the memory a 35 and the registered user information User authentication can be performed by comparing the unique identification number (Bluetooth ID or secret key) of the user terminal 11 with the unique identification number. In this case, even if there is no separate operating system 100 or if a failure occurs in the network with the operating system 100, user authentication is possible. Of course, in order to authenticate the user, the control unit a 34 transmits the unique identification number (Bluetooth ID or secret key) of the first user terminal 11 to the operating system 100 side through the communication processing unit a 36, The service operating unit 110 of the server 100 may perform user authentication and return the information through the information stored in the database 115. [

It is also possible for the control unit a 34 to store the return event itself in the memory a 35 or to transmit it to the operation system 100 and store it in the database 115.

In the above description, the first AP 30 recognizes the user when the user having the first user terminal 11 returns to the room from the outside of the house, automatically opens the door 70, and updates the home record. Of course, when returning from the room indoors, the same process is performed through the second AP 40 to automatically open the door 70 and update the outgoing record.

At this time, the process of authenticating the user can be omitted, unlike the case of returning home. However, the process of storing the entry / exit status must be done in order to ascertain the status of attendance.

On the other hand, an algorithm for correctly determining whether the user is going out or going out even when entering or exiting through the first user terminal 11 should be applied. In order to apply this algorithm, the control unit 34 of the first AP 30 can not store the access record, and the first user terminal 11 must be the main body to transmit the access record.

That is, the application control unit c 11-4 of the first user terminal 11 is connected to the first BLE module a 31 and the second AP 40 of the first AP 30 in cooperation with the distance determination unit c 11-3, The signal intensity of the first BLE module b 41 is traced so that the signal of the first BLE module a 31 becomes gradually stronger and weaker and the signal of the first BLE module b 41 becomes gradually stronger and weaker It is judged as a legitimate home, and then the home recording is transmitted to the operating system 100 through the communication module c (11-1). The service operating unit 110 of the operating system 100 can update the access record of the user by storing the return record received through the communication unit 105 in the database 115. [

The reason why the first AP 30 and the first user terminal 11 are connected is to receive the secret key stored in the first user terminal 11 to open the door 70. Accordingly, even if the user enters the area of the second AP 40 past the common porch, it is not necessary to perform the connection again with the second BLE module b 42.

4 and 5, the accessing process using the first smart card 21 has been described, and the accessing process using the first user terminal 11 has been described with reference to FIGS. 6 and 7. FIG. As can be seen from the above description, in the accessing process using the first smart card 21, only the signal transmitted from the first smart card 21 is scanned through the third BLE module 33 and 43, ). However, when the first user terminal 11 is used, it can be seen that a pairing and a secret key verification process are included. This takes into account the security characteristics of the user equipment.

That is, in the case of the smart cards 21, 22, and 23, there is little risk of manipulation or hacking unless the inside is remodeled. Therefore, sufficient user authentication is possible only by confirming the unique identification number (beacon ID) of the smart cards 21, 22, and 23.

However, since the user terminals 11, 12, and 13 of the smart phone or the like may be manipulated by changing the Bluetooth ID, the door 70 should not be opened only by checking the Bluetooth ID. Therefore, by requesting the secret key through pairing, it is confirmed whether the terminal has a legitimate secret key.

FIG. 8 is a flowchart for explaining a process of opening a door and checking an entrance when a plurality of user terminals simultaneously pass through a common entrance entrance control method according to an embodiment of the present invention. FIG. FIG. 7 is a block diagram illustrating a signal flow between terminals. FIG.

That is, in FIG. 6, the door 70 is opened and the door 70 is opened or closed during the entrance and exit of the first user terminal 11. However, when a plurality of users simultaneously access the door 70, And check whether access is made.

For example, it is assumed that the first user terminal 11, the second user terminal 12, and the third user terminal 13 access the common porch for returning at the same time. In the first AP 30, the first BLE module a 31 and the second BLE module a 32 all transmit (publish) a unique Bluetooth signal. Accordingly, all of the first to third user terminals 11, 12, and 13 operating in the Central mode can scan (S805) signals of the first BLE module a 31. Of course, the user terminals 11, 12 and 13 can also scan signals of the second BLE module a 32.

The terminal that has first confirmed that the signal strength of the first BLE module a 31 is higher than a predetermined level is connected (paired) with the second BLE module a 32. For example, if the first user terminal 11 is the closest to the common entrance, the first user terminal 11 and the second BLE module a 32 are connected (S810). The second BLE module a 32 operating in the peripheral mode is connected to the first user terminal 11 and simultaneously stops (S815) signal transmission (posting). Also, the second BLE module a (32) can be connected to only one Central mode device.

Accordingly, the second user terminal 12 and the third user terminal 13 can not confirm the originating signal of the second BLE module a 32 according to the connection between the first user terminal 11 and the second BLE module a 32 It is impossible to connect, of course.

The connection (pairing) between the first AP 30 and the user terminal is performed in order to open the door 70 by checking the secret key. Accordingly, when the door 70 is opened once, all the users moving at the same time can pass through it, so that it is not necessary to be connected to several user terminals. The controller a 34 checks the secret key received from the first user terminal 11 at the same time as the second BLE module a 32 and the first user terminal 11 are connected, S820>.

However, since the object of the present invention is not only to open the door 70 which is convenient but also to accurately check the passengers, it is necessary to carry out a process of storing access records for all users. To this end, the first AP 30 is provided with a plurality of BLE modules a (31, 32, 33) operating in different modes.

That is, even if the second BLE module a 32 is connected to the first user terminal 11, the first BLE module a 31 operating in the Advertiser mode is still transmitting (publishing) its own Bluetooth signal. Accordingly, the second user terminal 12 and the third user terminal 13 can acquire the broadcast signal of the first BLE module a 31 (S825), and if the intensity of the signal exceeds a predetermined level, The home record of the user can be transferred to the operating system 100 and updated (S835) to the database 115.

Of course, since the first user terminal 11 is connected to the second BLE module a 32 for opening the door 70, the controller a 34 of the first AP 30 is connected to the first B- Update the record (S830).

Here, the recording of the eaves of the first user terminal 11 may also be carried out by transmitting to the operating system 100 through a dedicated application installed in the first user terminal 11. [

In the process of FIG. 8, it is possible to apply an algorithm for judging whether or not a reliable return is possible, which can be inferred from the process of FIG.

10 is a flowchart for explaining a process of opening a door and checking an entrance when a user terminal and a smart card are mixed in a common entrance entrance control method according to an embodiment of the present invention, 10 is a block diagram for explaining a signal flow between an AP, a user terminal, and a smart card in the process of FIG.

For example, a user having the first user terminal 11, the second user terminal 12 and the third smart card 23 returns to the room from the outside of the room and simultaneously the first smart card 21, 22 and the third user terminal 13 are out of the room outdoors and the first user terminal 11 is closest to the common entrance.

When the first user terminal 11 that receives the broadcast signal transmitted from the first BLE module a 31 of the first AP 30 strongly or more than the reference is connected with the second BLE module a 32, (32) stops the transmission (S1010). Then, the controller a 34 receives the secret key from the first user terminal 11 connected to the second BLE module a 32, performs authentication, and opens the door 70. At the same time, the control unit 34 updates (S1015) the record of return to the first user terminal 11. Of course, the update of the home record may be performed by transmitting a dedicated application of the first user terminal 11 to the operating system 100 after passing through the sure access check algorithm described above.

The second user terminal 12 which can not be connected to the second BLE module a 32 acquires the posting signal of the first BLE module a 31 and transmits a home record to the operating system 100 via the dedicated application < do.

The third BLE module a 33 can recognize the third smart card 23 and transmit (or store) the home record to the third smart card 23 (S1025).

In this situation, the first smart card 21 and the second smart card 22 attempting to go out through the same common entrance are recognized by the third BLE module b 43 of the second AP 40, The third user terminal 13 acquires the broadcast signal of the first BLE module b 41 of the second AP 40 and transmits the outgoing record to the operating system 100 in step S1035 . Of course, if the third user terminal 13 tracks the signal strength of the first BLE module b 41 of the second AP 40 and confirms that the signal strength is within a certain distance, it can attempt connection with the second BLE module b 42. However, the second BLE module b 42 and the third user terminal 13 are connected to open the door 70 by confirming the secret key. When the door is opened through the connection of the first user terminal 11 The connection between the second BLE module b 42 and the third user terminal 13 is not necessary or a special operation accompanying the second BLE module b 42 does not occur.

Similarly, since the door 70 is opened through connection of the first user terminal 11, the remaining second user terminal 12 and the first to third smart cards 21, 22, It is not necessary to output the open signal 70, and only the access record check process is performed.

In the above description, the first BLE modules 31 and 41 operating in the Advertiser mode, the second BLE modules 32 and 42 operating in the Peripheral mode, and the third BLE modules 33 and 43 operating in the Observer mode, Are described. Accordingly, even if a plurality of users simultaneously enter and exit, the door 70 can be opened and the entrance and exit can be checked. However, if the specific user terminal 11, 12, 13 tries to connect with the AP 30, 40 but the connection is delayed for an unknown reason, the door 70 may not be opened by another user.

For example, if the first user terminal 11 and the second user terminal 12 return home at the same time and the first user terminal 11 attempts to connect with the second BLE module a 32 of the first AP 30, The door 70 is not opened normally because the connection opportunity by the second user terminal 12 is removed until the failed connection is disconnected.

Hereinafter, an example of opening the door in a different manner in preparation for connection errors between the user terminals 11, 12, 13 and the APs 30, 40 will be described.

First, a special situation such as a connection error can be accommodated by having a plurality of second BLE modules operating in the peripheral mode in the AP.

12 is a block diagram for explaining another example of AP in the common entrance entrance control system according to the embodiment of the present invention. The AP shown in Fig. 12 may be a first AP installed on the outdoor side or a second AP installed on the indoor side, but it is regarded as a first AP 30 'installed on the outdoor side for convenience of explanation, Add a delimiter 'd' after the name.

The first AP 30 'shown in FIG. 12 is provided with two second BLE modules d (31', 32 ') that do not have a BLE module operating in Advertiser mode and operate in Peripheral mode. That is, the second-1 BLE module d (31 ') and the second-second BLE module d (32') operate in the peripheral mode. The remaining control unit d '34', the memory d 35 'and the communication processing unit d' 36 'are replaced by the description of the same configuration of the first AP 30 ahead.

It is assumed that the first user terminal 11 and the second user terminal 12 return home at the same time with the first AP 30 'installed on the outdoor side. The Bluetooth module c 11-2 of the first user terminal 11 can recognize both the 2-1BLE module d 31 'and the 2-2BLE module d 32', and the distance determiner c (11-2) and the BLE module d (31 ', 32 (32)), the app controller (11-4) determines whether the Bluetooth module (11-3) ') Are connected. For example, the first user terminal 11 may attempt to connect with the second-2 BLE module d 32 '.

However, an unknown error may occur in the connection process between the first user terminal 11 and the second BLE module d (32 '), and the connection may be delayed. In this case, since the secret key can not be transmitted from the first user terminal 11 to the first AP 30 ', the door 70 is not opened.

However, it is possible to open the door 70 by accessing the second user terminal 12 which is returning together. That is, the first user terminal 11 is attempting to connect with the second-second BLE module d 32 'so that the second user terminal 12 can not recognize the second-second BLE module d 32' If the second user terminal 12 and the second BLE module d 31 'are connected after confirming that the second BLE module d 31' is approaching within a certain distance through the signal strength, So as to output the door opening signal.

Of course, access control is also checked in the control unit d (34 ') or through dedicated applications of the user terminals (11, 12). That is, even if a connection failure occurs in the specific user terminals 11 and 12, since each of the user terminals 11 and 12 has scanned at least one of the BLE modules d '31' and 32 ' To the system 100 side.

13 is a block diagram for explaining another example of an AP in a common entrance entrance control system according to an embodiment of the present invention. The AP shown in Fig. 13 is regarded as the first AP 30 '' installed on the outdoor side, and the division designation 'e' is added after the construction name.

The first AP 30 '' shown in FIG. 13 includes a first BLE module e 30 '' operating in Advertiser mode, a second 1-1,2-2 BLE module e 32 '', 33 'operating in Peripheral mode, ') And a third BLE module e (34' ') operating in the Observer mode. The remaining control unit e (35 ''), the memory e (36 '') and the communication processing unit e (37 '') are replaced by the description of the same configuration of the first AP 30 ahead.

It is assumed that the first user terminal 11, the second user terminal 12, and the third user terminal 13 are returning at the same time with the first AP 30 '' installed on the outdoor side. The first and second BLE modules e (31 &quot;, 32 &quot;, 33 &quot;) operating in Advertiser mode or Peripheral mode all broadcast signals. Therefore, the user terminal 11, 12, 13 can scan all three BLE modules e (31 ", 32", 33 ") and determine the distance using any of these signal strengths can do. However, if the 2-1, 2-2 BLE module e (32 ", 33") operating in the peripheral mode is attempting to connect to or connect to a particular user terminal (11, 12, 13) It is preferable to determine the distance through the signal strength of the first BLE module e (31 '') which always transmits the broadcast signal.

If it is confirmed by the first user terminal 11 that the first BLE module e (31 '') is approaching within a predetermined distance through the signal strength, it is connected to the second BLE module e (33 '') The door 70 can be opened. However, if a failure occurs in the connection process between the first user terminal 11 and the second BLE module e 33 '', the door 70 can not be opened. At this time, the second user terminal 12 returning home together And the door (70) can be opened by transmitting the secret key by connecting with the second-first BLE module e (32 ").

In addition to the opening of the door 70, an access record check is performed through a dedicated application of the control unit e (35 '') or the user terminal (11, 12, 13). Even if a connection failure occurs in the specific user terminals 11, 12 and 13, since the signals of the first BLE module e 31 '' are unconditionally scanned by the user terminals 11, 12 and 13, To the operating system 100 side.

12 and 13, in order to solve the problem that the door 70 is not opened when a Bluetooth connection failure of a specific user terminal 11, 12, 13 occurs, a plurality of BLE modules operating in a peripheral mode are provided An example is described.

12 and 13, the third BLE module d, e (33 ', 34' ') operating in the Observer mode checks the smart cards 21, 22 and 23 to open the door, To be checked.

In addition, in the example of FIGS. 12 and 13, it is possible to accurately grasp whether the user approached the common porch and returned or not, through the signal strength tracking of the outdoor and indoor APs.

In FIGS. 12 and 13, a plurality of BLE modules operating in a peripheral mode can be provided so as to prepare for connection failure of specific user terminals 11, 12, and 13, thereby opening the door 70. However, in a process of connecting with a plurality of BLE modules operating in the peripheral mode, an error may occur in all of the plurality of user terminals 11, 12, and 13. For this purpose, the door 70 may be opened and checked for access without any connection (pairing) between the user terminals 11, 12, 13 and the AP. An example of this is shown in Figs. 14 to 16, respectively.

First, the first AP 130 shown in FIG. 14 includes a first BLE module f 131, a third BLE module f 133, a controller f 134, a memory f 135, and a communication processor f 136. 'F' after each component name is only a division mark and does not have any special meaning.

The first BLE module f (131) operates in the Advertiser mode and the third BLE module (133) operates in the Observer mode. That is, the BLE module operating in the Peripheral mode is not provided in the first AP 130.

In this case, it is assumed that the first user terminal 11, the second user terminal 12, and the user having the first smart card 21 return home at the same time.

Since the first smart card 21 operates in the Advertiser mode for continuously broadcasting the beacon signal, the third BLE module f (133) tracks the signal strength of the first smart card 21 and confirms that it approaches within a predetermined time , The controller f 134 compares the registered user information (occupant information) stored in the memory f 135 with the registered user information and then outputs the opening signal of the door 70 to the door driving unit 60, Stored). Of course, when the first smart card 21 approaches the first, the door 70 opening signal is output through the first smart card 21. If the other user terminals 11 and 12 approach the control terminal f (134) Checks only access to the first smart card 21.

It is assumed that the user terminals 11 and 12 are approaching the first smart card 21 first. The first BLE module f (131) operating in the Advertiser mode steadily posts the signal. Accordingly, the user terminal 11, 12 can scan the signal of the first BLE module f (131) and determine the distance through the signal strength.

If the second user terminal 12 first accesses the first AP 130, the dedicated application installed in the second user terminal 12 is within a certain distance with the unique identification information of the first BLE module f 131 And transmits the information to the operating system 100.

The operation system 100 receives the unique identification information of the first BLE module f 131 from the second user terminal 12 via the communication unit 105 and the service operation unit 110 transmits the unique identification information of the first BLE module f The first AP 130 corresponding to the identification information is checked and a command to open the door 70 is issued to the first AP 130 through the network and the door 70 is opened in the communication processing unit f 136 of the first AP 130, Upon receiving the open command, the door 70 can be opened by the controller f (134) outputting the door 70 open signal to the door driver 60 side.

In addition, the service operating unit 110 of the operating system 100 performs an access check (eavesdropping) with respect to the second user terminal 12. The first user terminal 11 can recognize the first BLE module f 131 and send the unique identification information of the first BLE module f 131 to the operating system 100, May be stored in the operation system 100. [0050]

14 shows a method of opening the door 70 via the operating system 100 instead of opening the door 70 by connecting (pairing) the first AP 130 and the user terminals 11 and 12 The problem that the door 70 is not opened due to the Bluetooth connection failure can be solved.

In the first AP 130 shown in FIG. 14, the Advertiser mode and the Observer mode may be configured as one integrated BLE module, and then the operation control may be performed by the controller f (134).

The remaining functions of the control unit f (134), the memory f (135), and the communication processing unit f (136) will be replaced with the same description of the same configuration.

15 is another example of the first AP 230. [ 15 includes a Wi-Fi module g 231, a third BLE module g 233, a control unit g 234, a memory g 235 and a communication processing unit g 236, The 'g' after each configuration name is a delimiter.

The Wi-Fi module g 231 is provided for connecting the Wi-Fi module c 11-7 of the user terminal 11, 12, 13 with the Wi-Fi communication channel. The third BLE module g (233) operates in the Observer mode for scanning the Bluetooth signal.

15, the first AP 230 does not include the BLE module operating in the Advertiser mode or the Peripheral mode, unlike the previous examples, but the Wi-Fi module g 231 may substitute the BLE module.

That is, the Wi-Fi module g 231 outputs a unique Wi-Fi signal. When the user terminals 11 and 12 enter the vicinity of the first AP 230, the Wi-Fi module c The Wi-Fi module c 11-7 of the user terminals 11 and 12 and the Wi-Fi module 11-7 of the first AP 230 confirm that the signal strength of the Wi- g 231 is connected to the communication channel so that the secret key stored in the user terminals 11 and 12 is transmitted to the first AP 230 and then the authentication process is performed so that the controller g 234 outputs the door 70 opening signal can do.

Of course, the control unit g 234 stores the access record of the user through the unique identification information (device name or secret key) of the user terminal 11,12 through which the communication channel is connected through the Wi-Fi module g 231 to the memory g 235 Or transmits it to the operating system 100 side.

Unlike the BLE module operating in the peripheral mode, the Wi-Fi module g 231 can continuously transmit a Wi-Fi signal even when it is connected to the specific user terminals 11 and 12, 12 at the same time. Therefore, even if only one Wi-Fi module g 231 is provided, the Wi-Fi signal can be transmitted to the plurality of user terminals 11 and 12 and can be connected at the same time, so that the connection failure of the specific user terminal 11, 12 to the opening of the door 70, and does not interfere with the opening of the door 70.

On the other hand, the Wi-Fi module c (11-7) of the user terminals 11 and 12 can scan a plurality of Wi-Fi signals, but can only connect to devices having strongest signals or registered in advance. That is, when another Wi-Fi signal is more strongly output in the vicinity of the first AP 230, the user terminals 11 and 12 may not be able to open the door 70 by making a Wi-Fi connection with another device other than the first AP 230 There is also.

Such a problem can be solved through a dedicated application installed in the user terminals 11 and 12. That is, the app control unit c (11-4) can trace the WiFi signal for the device name registered in advance for opening the door among the simultaneously detected WiFi signals, so that connection is preferentially performed.

However, even if the priority connection for the first AP 230 registered in advance through the dedicated application is established, if the user terminals 11 and 12 are already connected to other Wi-Fi devices, There is a problem that the Wi-Fi module g 231 of the first AP 230 can not be connected. For example, the user terminals 11 and 12 are always connected to portable WiFi routers that receive mobile communication signals (WiBro, 3G, LTE, etc.) and convert them into Wi-Fi signals for transmission. In this case, the door 70 can be opened through the operation system 100.

For example, if the second user terminal 12 accesses the first AP 230 in a state where the second user terminal 12 is already connected to another Wi-Fi device, the Wi-Fi module c (11-7) It is possible to scan the transmission signal of the Wi-Fi module g 231 of the Wi-Fi module 230. That is, the Wi-Fi module c 11-7 of the second user terminal 12 can acquire the unique identification number (device name) of the Wi-Fi module g 231.

Accordingly, the application control unit c (11-4) of the second user terminal 12 receives the unique identification number (device name) of the Wi-Fi module g (231) acquired from the Wi-Fi module c (Device name) stored in advance in the storage unit c (11-5) at the time of installing (or later updating) the unique identification number (device name) To the system 100. Of course, when the unique identification number (device name) of the Wi-Fi module g (231) is scanned, the app controller c (11-4) does not transmit directly to the operating system 100 but transmits it when it is above a predetermined signal strength.

The operation system 100 receives the unique identification information (device name) of the Wi-Fi module g 231 from the second user terminal 12 via the communication unit 105 and the service operation unit 110 receives the unique identification information The first AP 230 corresponding to the unique identification information is checked through the network and the door 70 is opened to the first AP 230 via the network and the communication processing unit g 236 of the first AP 230 Upon receiving the door 70 opening command, the door g 70 can be opened by the control unit g 234 outputting the door 70 opening signal to the door driving unit 60 side.

In addition, the service operating unit 110 of the operating system 100 performs an access check (eavesdropping) with respect to the second user terminal 12. In addition, the first user terminal 11 simultaneously accessing can recognize the Wi-Fi module g 231 and transmits the unique identification information of the Wi-Fi module g 231 to the operating system 100, 1 access check to the user terminal 11 may be stored in the operating system 100.

On the other hand, since the first smart card 21 operates in the Advertiser mode for continuously broadcasting the beacon signal, the third BLE module g 233 tracks the signal strength of the first smart card 21 and approaches The control unit g 234 compares the registered user information (resident information) stored in the memory g 235 to perform authentication, outputs the door opening signal to the door driving unit 60, (Save your ears). Of course, if the first smart card 21 approaches first, the door 70 opening signal is outputted through the first smart card 21. If the other user terminals 11 and 12 approach first, the control g (234 Checks only access to the first smart card 21.

In FIG. 15, an example has been described in which the door 70 is opened using a Wi-Fi signal in place of the Bluetooth signal and the access check is performed. That is, when a Bluetooth signal is used, a failure may occur in the connection (pairing) process, and since only one user terminal 11, 12, 13 can be connected to one BLE module, The problem that the door 70 is not opened when a connection (pairing) failure occurs is solved.

Meanwhile, the user terminals 11, 12, and 13 basically operate in the Central mode for scanning and connecting the Bluetooth signal. However, in recent years, the user terminals 11, 12, and 13, which also support the Advertiser mode function for periodically posting specific Bluetooth signals (beacon signals) (11, 12, 13) are being released.

In this case, the AP can perform door (70) opening and access check even if there is no BLE module or Wi-Fi module operating in Advertiser mode or Peripheral mode. An example of an AP for this is shown in FIG.

Referring to FIG. 16, the first AP 330 includes a third BLE module h 333, a controller h 334, a memory h 335, and a communication processor h 336. The third BLE module h 333 operates in the Observer mode for scanning the Bluetooth signal.

In addition, both the user terminals 11 and 12 and the first smart card 21 operate in an Advertiser mode in which beacon signals are continuously posted.

Therefore, if the user terminal 11, 12 and the first smart card 21 access the first AP 330 at the same time, the user terminal 11, 12 and the first smart card 21 ), And it is possible to identify a user device that approaches the reference distance first by tracking the signal strength. Then, the controller h 334 compares the registered user information (occupant information) stored in the memory h 335 to determine whether the user equipment is an authorized user, and then outputs a door opening signal to the door driving unit 60.

In addition, the control unit h 334 stores and records access records for all user devices 11, 12, and 21 scanned by the third BLE module h 333.

Although the drawings and descriptions above deal with APs that apply various methods for door 70 opening and exit check, all functions are included in the AP and can be controlled as needed.

For example, the AP includes a first BLE module (Advertiser mode), a second-first BLE module and a second-BLE module (ideal peripheral mode), a third BLE module (Observer mode), a Wi-Fi module, .

In this case, the beacon devices such as the smart cards 21, 22, and 23 and the user terminals 11, 12, and 13 supporting the Advertiser mode scan the Bluetooth signal through the third BLE module, Residents information) and can check access while outputting an opening signal of the door (70).

In addition, the user terminal (Central mode) with smooth Bluetooth connection can be connected to the 2-1BLE module or the 2-2BLE module to transmit the secret key, and the door 70 can be opened and checked.

In addition, a user terminal (Central mode) in which a bluetooth signal is smoothly scanned but is not smoothly connected, after the Bluetooth signal of the first BLE module, the second-first BLE module, or the second-second BLE module is scanned, To the operating system 100, and the operating system 100 commands the opening of the door 70 to the AP so that the door can be opened and checked.

In the case of a user terminal that does not smoothly scan the Bluetooth signal or Bluetooth mode is turned off, it may be connected to the Wi-Fi module of the AP to check the door opening and accessing, or the unique identification information (device name) of the Wi- To the operating system 100 so that the door opening command is transmitted from the remote and the entrance check is performed.

As described in detail above, according to the present invention, the smart card 21, 22, 23 for generating a beacon signal or the user terminal 11, such as a smart phone or a tablet PC, 12 and 13 perform Bluetooth communication with the AP, it is possible to automatically open the door 70 after confirming that the user is a legitimate user even if the user does not perform another action, thereby increasing convenience.

In addition, by storing the access record of whether the user has made a return home or not at the same time as the automatic opening of the door 70, the rescue situation can be grasped accurately after occurrence of an emergency such as a fire or the like.

In particular, since a plurality of BLE modules operating in different modes are loaded in the AP, even if several persons attempt to access at the same time, the access record can be accurately grasped and the status of the occupant can be established.

In addition, since the entrance and exit records are stored after determining whether the access is actually made through the signal strength tracking algorithm of the AP installed in the outdoor and the indoor, respectively, it is possible to accurately construct the occupant status even after returning after accessing the common entrance.

In addition, if a plurality of BLE modules operating in the peripheral mode are provided in the AP, or if a Wi-Fi module is provided, the other user terminals 11, 12, and 13 So that the door can be opened.

In addition, after the user terminals 11, 12, and 13 scan the unique identification information of the AP (the unique ID of the BLE module or the device name of the Wi-Fi module), the user terminal 11 may request door opening to the operating system 100 side through a dedicated application So that even if a connection failure occurs between the user terminals 11, 12, 13 and the AP, door opening can be smoothly performed.

In the above description, only the common entrance which is connected to the first floor or the parking lot of the apartment house is described, but the common entrance entrance control system according to the present invention can also be applied to the roof door. In other words, even if the rooftop door is kept locked to prevent crime, it is possible to install the AP on the roof and automatically open when the user equipment with the access right is approached.

In the case of common entrance, all registered residents should be allowed access. However, in case of special entrance such as rooftop, it is possible to allow entrance only to adults who are registered as administrator among residents, and to restrict access to children. Of course, in the event of an emergency such as a fire in the common entrance or rooftop door, automatic opening should be made so that evacuation is possible quickly.

Also, access to the common entrance is not necessarily limited to the absence of registered user terminals (11, 12, 13) or smart cards (21, 22, 23). The door 70 can be opened by inputting a password of the lobby phone 50, inputting a fingerprint, or calling the household when returning home. have.

In addition, there may be a case where an abnormality occurs in the network or the power of the user terminals 11, 12, 13 is turned off. In this case, the door 70 can be opened by the password input through the lobby phone 50, the fingerprint input, the household call method, or the door 70 can be opened through NFC tagging or RFID tagging of the user equipment.

In addition, the dedicated application installed in the user terminals 11, 12, 13 is not only used for entrance and exit of the common entrance, but also can provide various services necessary for managing the apartment house. In other words, the operation system 100 provides a management fee confirmation and payment service through a dedicated application, noise measurement, control of IoT device in the household, community service, electronic voting or survey service, complaint reception, unmanned courier notification, Traffic, weather information, and second hand market.

Further, when APs are installed in various places in the apartment management area, it is possible to provide various services in cooperation with the user terminals 11, 12, 13 and the smart cards 21, 22, For example, when an elderly person or a child enters or passes through a certain AP area, it can be notified to a guardian. Or when the user enters the parking lot entrance with the user equipment, the user can perform the Bluetooth communication with the AP to automatically open the breaker through the user authentication. If the AP is installed for each parking lot or for each parking area, So that they are notified of parking or dedicated applications.

In the case of a visitor who is not a resident, it is also possible to provide a temporary access key after installing a dedicated application in advance.
